Methane On Mars May Indicate Living Planet 200

Riding with Robots writes "NASA is announcing today that the definitive detection of methane in the Martian atmosphere means the planet is still alive, at least geologically, and perhaps even biologically. 'Methane is quickly destroyed in the Martian atmosphere in a variety of ways, so our discovery of substantial plumes of methane in the northern hemisphere of Mars indicates some ongoing process is releasing the gas,' said one agency scientist. The gas was detected with observations made over over several Martian years with NASA telescopes at Mauna Kea, Hawaii. Both biological and geological processes could explain the methane."

ianchaos writes "There's no better way to assure the eventual destruction of mankind than by the event sponsored by Singapore's Defence Science and Technology Agency. Newscientist has a good writeup of the robot challenge, which is to build a robot that can operate autonomously in urban warfare conditions, moving in and out of buildings to search and destroy targets like a human soldier."
